非ST段抬高型急性冠状动脉综合征患者经皮冠状动脉介入术前强化他汀治疗对心血管事件的影响

目的 探讨非ST段抬高型急性冠状动脉综合征(NSTE-ACS)患者经皮冠状动脉介入(PCI)术前强化他汀治疗对心血管事件的影响.方法 100例NSTE-ACS患者完全随机分为2组,每组50例.常规他汀组PCI术前7 d给予辛伐他汀20 mg/d;强化他汀组PCI术前7 d给予阿托伐他汀40 ms/d.2组患者均接受其他常规治疗.比较2组在PCI前后心肌损伤标记物变化;观察随访1个月时患者主要心血管事件的发生率.结果 常规治疗组服药前、PCI术前及PCI术后肌酸激酶(CK-MB)分别为(18.94±24.35)、(13.57±6.42)、(15.39±10.08)μg/L;肌钙蛋白(TnI)分别为(0.82±3.09)、(0.46±1.38)、(0.82±2.52)μg/L;强化他汀组服药前、PCI术前及PCI术后CK-MB分别为(19.43±21.96)、(12.49±6.40)、(12.68±12.54)μg/L,Tnl分别为(3.18±9.53)、(0.61±2.51)、(0.72±0.47)μg/L.强化他汀组PCI术前较服药前下降,差异有统计学意义(P<0.05).NSIE-ACS患者PCI术前强化他汀治疗后CK-MB、ThI水平下降较常规他汀组更明显(P<0.05);PCI术后常规他汀组CK-MB、TnI水平的上升与强化他汀组差异有统计学意义(P<0.05).PCI术后随访1个月,常规他汀组心肌梗死1例(2.0%),靶血管再次血运重建2例(4.0%);强化他汀组无主要心血管事件发生.强化他汀组心血管事件发生率较常规他汀组低,但2组差异无统计学意义(P>0.05).结论 NSTE-ACS患者PCI术前强化他汀治疗较常规剂量他汀治疗能够减少术后心肌损伤.

Abstract：

Objective To observe the impact of aggressive statin treatment prior to percutaneous coronary intervention (PCI) in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS) on cardiovascular events.Methods One hundred NSTE-ACS patients were enroned and randomized into 2 groups:standard and aggressive statin treatment.The standard group received simvastatin 20 mg per day and the aggressive statin treatment group received atorvastatin 40 mg per day for 7 days prior to PCI,respectively.Both groups received other standard medical therapy.Biomarkers of cardiac injury were measured and compared before and after PCI.Major cardiovascular adverse events were evaluated during one month period of follow-up.Results Both CK-MB and TnI levels were significantly reduced after aggressive statin treatment compared to standard dose(P<0.05).After PCI,CKMB and TnI levels were significantly elevated in NSTE-ACS patients with standard dose than in patients with aggressive statin treatment(P<0.05).Major cardiovascular adverse events were reduced in aggressive statin treatment group,however,no statistical difference was observed between the two groups.Conclusion Aggressive statin treatment prior to PCI may be more effective in reducing post-PCI myocardial injury than normal dose of statin therapy in NSTE-ACS patients.

阿托伐他汀干预对急性冠状动脉综合征患者PCI术后粘附分子水平的影响

Objective To explore the impact of different dose atorvastatin on the adhesion molecules level in the acute coronary syndrome (ACS) patients who had received percutaneous coronary intervention (PCI). Methods Eighty-eight ACS patients were divided into three groups, group A (normal treatment group), group B (normal treatment plus atorvastatin 10mg per day) and group C (normal treatment plus atorvastatin 80mg per day). The patients in group B received atorvastatin 10 mg per day orally before PCI and after PCI subsequently, and the patients in group C received atorvastatin 80 mg per day orally before PCI and after PCI subsequently for three days, then the dose of atorvastatin was decrease to 10 mg per day. The concentrations of soluble intercellular adhesionmolecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were detected before PCI and at the 3rd, 7th 14th day after PCI. Results At the 7th day, the concentrations of sICAM-1 and sVCAM-1 in group C were significantly lower than those in group B, which showed sICAM-1 (68.35±23.80) μg/L vs (131.45±29.12) μg/L and sVCAM-1 (251. 65±36.61)μg/L vs (334.87±32.98) μg/L, respectively. Compared to group A, the adhesion molecule level in group B and group C were significantly decreased (P<0.05) and had no obviously affect on blood fat level. Conclusion The treatment of atorvastatin could significantly decrease the adhesion molecules' level after PCI, which may play an important role in lowing inflammation and coronary artery restenosis after PCI.
